No. 64,065 m Patented April 23, I867.

UNITED STATESPATENT OFFIC i I V 1 JOHN K. BOSWELL, OF RICHMOND, INDIANAPIMPROVEAMENT IN FRUIT-DRIERS.

Specification forming part of Letters Patent No. 64,065, dated April 23,1867; antedated March 16, 1867.

. by declare that the following is a full, clear,

and exact description of the same, reference being had to theaccompanying drawings,

making a part of this specification, in which Figure 1 is a perspectiveview; Fig. 2, a transverse section; and Figs. 3, 4, and 5, sections ofthe heating apparatus.

Similar letters of reference when they occur in the different figuresrepresent corresponding parts of the invention.

This invention is designed as an improve ment on my patent of September4, 1866, for a dry-house, by which improvement a better control of theheat is obtained, and the invention may also be adapted to the differentpurposes indicated in the name.

To enable others skilled in the art to make and use my invention, I willproceed to de-' scribe it with reference to the drawings.

A, Fig. 1, represents the rectangular house or structure, with the doorsthrown open, and a hinged section of the top F, forminga lid, raised. Nrepresents the furnace, the mouth of which is shown in Fig. l, withash-pan, and a vertical slide for regulating the draft. D represents atriangular revolving heater, and b a shield or covering for the furnaceN, heater D, and a horizontal section of pipe or chimney K, and issecured to the floor of the structure by nails, or any suitable means. drepresents ahinged section of the shield, forming a door for access tothe heater, and also for regulating the amount of heat escaping from theheater D into the structure. The shield b is also provided with tonguedapertures n a n, for the admission of heat into the structure when thedoor 'D is closed.

0, 'Fig. 1, represents a horizontal sliding panel, formingavapor-chamber in the top of the structure, of which the panel 0 is thebottom.

H is a pipe connecting between the structure above panel 0 and thechimney K. r r is a valve for opening and closing pipe H.

The relation of the furnace N, revolving triangular heater D, andchimney-K, is shown in Figs. 3, 4, and 5. The tubes 1, Fig. 3, and j,Fig. 4, serve as axles for the revolving heater, and also allowcommunication be tween the furnace N, through the hollow heater D andthe chimney K, the aperture working on'tube i and tube j in aperture h.

D, Fig. 2, represents an end View of the tri' angular revolving heater;the lines 1) p 19 its motion; q q q q are outlines of the furnace, and bof the shield. The bottom of the structure is closed, exceptingunderneath the shield D, admitting only what air passes up through theshield. 15 t t are bearings secured in each end of the structure tosupport bars gor' holding fruit-drawers, clothing, bonnets,

The revolving triangular heater insures a better control of the heatthan is obtained in any other way, the heat being radiated more forciblyin direct lines from either of the sides, and, from its tendency torise, the heat may be thrown upward or to one side, according to theposition of the highest side of the heater.

The retention of the heat in the structure is regulated by the valve 9"r, and the current of ascending heat may be diverted from one end of thestructure to the other by means of the sliding panel C, which panel,being shorter than the structure, when it is slid to one end forces thecurrent to the other in order to escape through the pipe H. The heat mayalso be permitted to escape suddenly by raising lid F. As a room-warmingapparatus, the front doors are thrown open, and the heater turned withone side to the front, at an angle offorty-five degrees, with one of thesides upward.

The heater is also a convenient arrangement for heating smoothing-irons,and by laying thin strips of ,metal or other suitable material on theheater, to sprinkle the sulphur on, the apparatus is complete forbonnetbleaching.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is
